ful-Improvements in Excavating and Load? ing Machines; and I do hereby declare the following to be a full, clear, and exact d escri tion of the invention, such as will enab e others skilled in the art to which it appertains to make and use the same.

' y invention relates to excavating and loading machines designed more especially for employment in connection with railroad construction and repair trains for the excavation and transportationl of earth along the line of road and is an improvement on the excavating and loading machines patented to me June 3, 1902, and March 2, 1904, the Letters Patent being numbered, respectively,

The objectsl and nature of the present improvements will be readil comprehended,

reference being had to the ollowing detailedI description and to the accompanying drawings, illustrating the invention in its preferred form of embodiment, it being understood that various modifications may be made therein Without exceeding the scope of the concluding claims. A

In the drawings, Figure 1 is a side elevation of an excavating and loading machine embodying my invention. Fig. 2 is a top plan View. Fig. 3 is a front end elevation. Fig. 4 is a rear end elevation. Figs. 5, 6, 7, andS are detail views ofthe mast. Figs. 9, 10, 10a, and 11 are detail views ofthe boom. Fig. 12 is a detail view of the guide and adjustable lower brace. Figs. 13, 14, 15, and 16 are detail views of the upper brace for the guide and the support for said brace. Figs. 17, 18, 19, and 20 are detail views ofthe dipper.

The machine, the construction of which will now be setforth in detail, is, as above stated, designed more especially for use in railroad excavating and repair work, and to this end is supported on and movable along av train composed of flat-cars in a manner similar to that shown in my hereinabove-referredto patents. In view of the former disclosures complete illustration of the supporting and loading cars in connection with the present invention is unnecessary; but as an aid to the understanding of the construction there is shown in Fig. '4 a portion of a car-platform 1 and a crosssectional view of one'of the carsills 2.

The carrier-frame, which is supported directly upon and is movable longitudinally over the car-platform 1, comprises side members or runners 3 4, each composed of two I# beams having their forward ends bent upwardly and inwardly or otherwise fashioned to ride over obstructlons; a forward endinember 5, composed of a channel fastened 'at its ends' to channel corner-posts 6 7 and to the side members; a rearward end member consisting of two I-beams 8 9, spaced apart and fastened at their ends tothe side members; a central longitudinal member 10, consisting of an I-beam fastened at its ends to the end members, and truss-channels 11 11, joined at their ends by standard connections to the side members and central member. The corner-posts 6 7 are connected together at their upper ends by flanking channels 12 12 and are rigidly sup orted by longitudinal braces 13 and lateral races 14 of any desired construction.

Erected at the rearward end of the carrierframe is a frame of A form, consisting of two members 5 16, composed of channels, the

channels of each member being fastened at" l4. The A-rame member 18 is braced by bars 19, fastened thereto, to the side members 3 4 and 13'- tothe braces 13 by strip extensions 19. f

The machine is designed for excavating at either side of the track or line of road, and to this end is equipped with means permitting the shifting, among other parts, of the dipper-carrying boom and the mast from one side of the carrier-frame to the other. Secured to the channels 12 12 above each corner-post is a plate 20, on which is pivoted to swing horizontally a head 21, having a central opening to receive the pivot-bolt 22, which asses through astrap 23 and the plate 20. he boom 24, which is referably composed of a wooden beam anked by side channels of metal, is pivoted to one or the IOO other of the heads 21 by a bolt 25' passingmanner set forth in the above-referred-to patents. B the peculiar construction of `mounting, t e boom is easily and quickly shifted from one Aside of the machine to the other, dependent upon the side of the track to be worked.

The means connecting the dipper 27 with the free end of the boom likewise allows of the necessary adjustments to obtain the pro er operation of the dipper regardlessV of its ocation relatively to the right or left side of the machine. The dipper has a.bot-tom 28, which conforms cross-sectionally to the form ofditch to be made, sides 29 29, a top 30, and a door 31, which when closed forms' the back, the dipper being open at its front. In connection with the cutting edge 32 I may employ the usual teeth, showing of which is unnecessary. The cutting edge 32 is formedl separately from the bottom and sides of the dipper and is fastened thereto, as

shown in Fig. 17. Integral with said edge is a rearwardly-inclined iiange or rib 33, the function of which is to prevent the excavated material from adhering to the bottom of the dipper. inasmuch as the earth entering the dipper at its front is deeeted above the bottom by the action of the inclined flange or rib, the lowermost portion of the earth contents is not compacted on the surface of the bottom, and free discharge of the contents is therefore obtained. The door 31 is pivoted by strap-hinges 34 to the dipper-top 30, the

intle 35, which is common to bot hinges,

ein set back from the rear end, whereby the oor in opening swings clear of said end to allow free dumping of the entire contents. The door is fastened in its closing position by a slidable spring-pressed-bolt 36 thereon engaging a hook 37, rojectmg from the bottom 28, and is release by the ralslng of the bolt a ainst spring action through manipulation of a bell-crank.lever 38, having chain connection with the bolt. Secured to thesides of the dipper are bail members 39, which exi i To the under side of the asom tends a set-bolt 45. The dipper is thus vertically and -horizontally pivoted to the free end of the boom andwill assume a position approximately parallel with the side ofthe machine, regardless of whether the parts are located at the righ-t or left of the line of road.

The dipper. when in excavating position has ed to the proper position for excavating, tilting during such excavation being prevented by the engagement of an arm 46, pivoted on the boom, with a stop-flange 47 on the top of the clipper, which flange is of V form to allow the free end of the arm to self-center. The arm is attached'at its inner end to a sleeve 48, adjustable along the boom to determine the proper excavating position of the dipper.

The dipper is raised to dumping position over a car and lowered to excavating position at one side of the line of road by movement of the boom, which movement is controlled by an inclined guide 49, presently to be described. To minimize friction in the movement of the boom, the latter is equipped with a roller 50, which has end bearings in arms 51, pivoted between ears 52, secured to the boom on its under side. The inclined guide 49 is shiftable from one side of the carrierframe to the other, dependent upon the side of the line of road to be worked, and to bring lthe roller 50 to the right or left of the boom, as the case maybe, the arms 51 are rocked on their pivots 53, then adjusted position being maintained by a bolt 54, passed through holes in the arms and through holes 55, prov'ided in the ears 52.

The boom-hoisting chain or cable 56 is'. attached at one end to an eye on the boom near the free end ofthe latter and passes around a sheave 57 at the upper end of a mast 58 and thence around a sheave 59 at the base of the mast, after which it is connected with the source of power, which may be an enginedriven drum. (Not shown.) The chain runs over a roller 69 at the forward end of the carrier-frame. To maintain alinement ofthe groove of sheave 57 with the chain 56 in the hoisting and lowering of the boom, said sheave is mounted to swing laterally, being supported in a housing 61, which is pivoted in a hood 62, secured on the top of the mast 58. The top plate 63 of the housing is pivoted toward one end to the hood by a bolt 64, Which is in line with the vertical traverse of the cable, and said plate is provided toward its other end with a curved slot 65, loosely receiving a bolt 66, which is screwed or other- IIO wise fastened to the hood. Thus the housing and sheave may swing horizontally according to the change of angle of the inclined traverse of the chain, and the line of the sheave-groove and cable is maintained with the consequent minimum friction. In shifting the parts from one side of the machine to the other the position of the housing 61 is reversed and the bolt 66 becomes the pivot for the housing.

The mast 58 is composed of two channels 67, connected together at intervals by plates 68. The mast is shiftable from one side of the center of the carrier-frame to the other, and to this end is removably supported on the rearward framev member and in the A- frame. On the lower end of the mast are secured plates 69, from which project ears 70, having holes through which extend securingbolts 71, the latter also passing through ears 72 on a plate 73, removably fastened on the rear frame member. To allow of the shifting of the sheave 59 from one side of the mast to the other, two ears 74 75 are provided on the mast, which ears, together with a central box 76, form the bearings for the shaft 77 of the sheave. By reference more particularly to Fig. 6 it will be obvious that the sheave may be readily shifted from one side of the mast to the other for the purpose hereinbefore stated. Toward its upper end the mast is removably fastened between the A-frame members and between shoulders 78 79, the shoulders 79 being shiftable, as indicated by the dotted lines in Fig. 8.

The inclined guide 49 consists of an I beam or rail, bent to curve form and having at its lower end a hook-shaped stop 80 to limit the loweringmovement of the boom and dipper. To the upper. end of the guide is pivoted by a bolt 81 a guide extension 82, composed of two bars secured together in separated relation. rI`he guide is vertically supported by a bracerod 81Aof I form, removably secured at its upper erfdfby the bolt 8l to said guide and at its lower end to a shiftable bracket 83, fastened on the rear frame member. The guide folds at the pivot 81 when not in use, and in the folded condition the member 49 rests at its lower end adjacent to the side of the earrier-frame. This folding movement is permitted by disconnecting the guide member 82 from the mast, this being accomplished by withdrawing a pin 84, passed through holes in the mast and through holes 85 in said member 82, and also by moving inwardly a lower brace 86, which serves to hold the lower guide member at varying distances from the side of the machine. Said brace 86 consists of two bars secured together at intervals in separated relation and provided with a series of holes 87. The bars are slidable between the two I-beams of the rear frame' member and are fastened thereto to project therefrom at any desired distance by a pin 88, passed through holes inthe said beams and through any one of the holes 87 in said bars. The bars of the brace 86 are joined near their outer end and then separated to provide ears 89, between which are pivoted two clamping members 90, which hook freely over the inner flange of the I- guide and are secured together beyond the pivot by a bolt 91. The series of holes in the upper guide member and in the lower brace permit of different adjustments of the guidel to conform to the requirements in the Work to be performed. When the guide'is folded, the elevated boom is held against falling by engaging ashoulder 92 on the top of the A- frame, whereas when the guide is in position for service the upper guide member is adj usted to cause the boom to swing clear of the shoulder. Y

To prevent lateral movement -of the guide, a brace-rod 93 is provided to extend between the brace 86 and carrier-frame. Said rod has a hooked end 94, engaging with an eye 95 on the brace, and its other end has a series of holes 96 for adjustable engagement with a pin 97 onthe side frame member. By this provision the guide is stoutly braced regardless of its adjusted position relative to the side of the machine, and a similar pin 98 is provided at the opposite side to be engaged when the parts are shifted. The guide is further braced by a bridge-piece 99 adjustable along the members of the A-frame and having a recess 100, receiving the brace 81 and preventing lateral movement thereof. The bridge-piece is flanged at 101 102 to engage the A-frame members and is adjustably secured thereto by'a hook-bolt and nut 103.

The guide members are raised to a new position or folded, as desired, by a cable 104, which is fastened at one end to the brace 81 near the upper end of the latter and is intermediately passed around a sheave 105, mounted in the mast, and thence around a drum 106, journaled on the A-frame to be shiftable from one side to the other, as may become necessary, the drum having a handwheel 107 for its rotation and pawl-andratchet means 108 for locking it, as will be understood.
